### ⭐⭐⭐⭐⭐ Odor and dust killer!
*by L***R on August 29, 2022*

This does work. Cooking odors, pet odors and even dust are a thing of the past. House smells clean even after my son cooks!

### ⭐⭐⭐⭐⭐ Gaurdian UV Air purifier
*by J***. on November 7, 2025*

I could tell the difference in the freshness of air in our home within hours of it operating

### ⭐ NEEDS TO BE HARDWIRED - not a drop in replacement for old unit (updated)
*by C***E on December 30, 2022*

I bought this as a replacement for the old model. Says it comes with transformer but they don't tell you the transformer needs to be hardwired. Also cannot use the old plug in power supply as they have changed the voltage 12 to 24V and size of the connector is different. Also the mounting plate has different screw hole locations. I bought this power supply https://www.amazon.com/dp/B07VV1X6JV?psc=1&ref=ppx_yo2ov_dt_b_product_details and a connector adapter. Was looking for an easy switch out, now it's turned into a major project - disappointed but made it work eventually. Amazon vendor was responsive and tried to help. NOTE: Power supply that pops up with QR+ description was 12V and not appropriate.
